Description
New data are presented on the resonant Auger decay of iodobenzene (C<sub>6</sub>H<sub>5</sub>I) in the region of the I 4d<sup>–1</sup> ionization threshold. The excited molecules decay by participator and spectator processes to populate single-hole valence states and two-hole, one-particle excited states of the cation, providing new information on the structure of C<sub>6</sub>H<sub>5</sub>I<sup>+</sup>. Excitation of dissociative C<sub>6</sub>H<sub>5</sub>I (I 4d<sub>5/2,3/2</sub><sup>–1</sup>)σ* resonances can, in principle, result in ultrafast dissociation to C<sub>6</sub>H<sub>5</sub> + I** and the subsequent autoionization of I**, but no evidence for this process is observed. Finally, the results are compared with our recent study of the resonant Auger decay of methyl iodide (CH<sub>3</sub>I).. Authors: Pratt, Stephen T.
